Description

Technical Field

[0001] The present application relates to the technical field of power grid installation, and in particular to a main power grounding grid installation structure. Background Art

[0002] During the power construction process, cable laying is an important part of substation construction. Power cables are usually buried in cable trenches within the station, or placed on pre-designed bridge paths. This process requires the cable laying bridge path to be designed in advance by computer, and then the cable laying simulation is performed based on the designed bridge path. Finally, data such as the number, length, and sorting of cables are obtained, and an intuitive cable laying route diagram is generated.

[0003] According to existing technologies, cables are often excessively bent after being removed from the rollers. This not only occupies more space during grid installation, requiring longer cables for the same distance, resulting in material waste, but also lacks a stable guide structure during cable transportation, making it prone to deviation or even deviation from the conveying path, impacting the stability of subsequent straightening operations. Furthermore, during the straightening process, friction between the straightening wheel and the cable generates heat. Heat accumulation can damage the cable's outer surface, impacting cable performance. Utility Model Content

When laying the power grid, the bent cable not only occupies a large space, but also requires longer cables for the same distance, resulting in cable waste.
